Generated api module use Fetch Api or Axios to make requests.



Any questions you can ask here or in our slack(#swagger-typescript-api channel)


✨ The fork key differences

  • Axios v0.27.2+ support
  • Updated dependencies to eliminate vulnerabilities
  • Merged features and fixes from next to master and some commits from origin pull requests:
    • Docs: added "generateClient", "typePrefix", "typeSuffix" options to readme for NodeJS usage (#335)
    • Feature: add an option to disable throwing an error when request.ok is not true (#297)
    • Feature: add a parameter to sort types and types properties (#299)
    • Feature: load prettier config from your project by default (#286)
    • Feature: allow passing "patch" option to "swagger2openapi" (#283)
    • Fix: missing title of object type (#303)
    • Fix: reject and exit with code 1 if error (#295)
    • Fix: missing extractRequestBody field in type
    • Fix: problem with missing HttpResponse type with --to-js option

const { generateApi } = require('swagger-typescript-api-nextgen');
const path = require("path");
const fs = require("fs");

/* NOTE: all fields are optional expect one of `output`, `url`, `spec` */
generateApi({

    parser: "typescript",
  },
  defaultResponseType: "void",
  singleHttpClient: true,
  cleanOutput: false,
  enumNamesAsValues: false,
  moduleNameFirstTag: false,
  generateUnionEnums: false,
  typePrefix: '',
  typeSuffix: '',
  extraTemplates: [],
  hooks: {
    onCreateComponent: (component) => {},
    onCreateRequestParams: (rawType) => {},
    onCreateRoute: (routeData) => {},
    onCreateRouteName: (routeNameInfo, rawRouteInfo) => {},
    onFormatRouteName: (routeInfo, templateRouteName) => {},
    onFormatTypeName: (typeName, rawTypeName) => {},
    onInit: (configuration) => {},
    onParseSchema: (originalSchema, parsedSchema) => {},
    onPrepareConfig: (currentConfiguration) => {},
  }
})
  .then(({ files, configuration }) => {
    files.forEach(({ content, name }) => {
      fs.writeFile(path, content);
    });
  })

πŸ’Ž options

--templates

This option needed for cases when you don't want to use the default swagger-typescript-api output structure

Templates:

How to use it:

  1. copy swagger-typescript-api templates into your place in project
  2. add --templates PATH_TO_YOUR_TEMPLATES option
  3. modify ETA templates as you like

NOTE:
Eta has special directive to render template in your Eta templates - includeFile(pathToTemplate, payload)
If you want to use some default templates from this tool you can use path prefixes: @base, @default, @modular.
@base - path to base templates
@default - path to single api file templates
@modular - path to multiple api files templates
Examples:
- includeFile("@base/data-contracts.eta", configuration)
- includeFile("@default/api.eta", configuration)
- includeFile("@default/procedure-call.eta", configuration)
- includeFile("@modular/api.eta", configuration)
- includeFile("@modular/procedure-call.eta", configuration)
- includeFile("@base/route-docs.eta", configuration)
- includeFile("@base/route-name.eta", configuration)
- includeFile("@base/route-type.eta", configuration)
- includeFile("@base/route-types.eta", configuration)

--module-name-index

This option should be used in cases when you have api with one global prefix like /api
Example:
GET:/api/fruits/getFruits
POST:/api/fruits/addFruits
GET:/api/vegetables/addVegetable
with --module-name-index 0 Api class will have one property api
When we change it to --module-name-index 1 then Api class have two properties fruits and vegetables

--module-name-first-tag

This option will group your API operations based on their first tag - mirroring how the Swagger UI groups displayed operations
